Since the early 1990s, the human security movement has sought to expand the concept of security beyond the traditional military defense of national borders to focus on the intra-state security needs of populations at the individual level. Specific initiatives frequently address problems of population health, ethnic conflict, religious extremism, human rights, environmental or natural disasters, and other critical issues. For expatriate human security workers in the field, the environment may present meaningful challenges to their wellbeing and productivity. This can be especially so for those who have relatively more experience in academic, business, or administrative settings, and less in the field. The authors' goal is to illuminate practices that have demonstrated their efficacy in enhancing wellness, sustainment, and productivity for human security and other humanitarian and development workers deployed to austere environments. The content represents a synoptic consensus of best general practices and guidance from a range of resources comprising United Nations agencies and activities, national and international non-governmental organizations (NGO's), private volunteer organizations (PVO's), national military services, and international business concerns.
